Operating Instructions and Parts List
Filter Disassembly
1.
Ensure pump is OFF.
Turn off any
automatic controls and lock out / tag
out switches and / or circuit breakers
to ensure the system cannot
inadvertently turn on.
Verify power is
removed from the
system. Disconnect, tag and lock out
power source before attempting to
install, service, relocate or perform any
maintenance.
2. Close filter isolation valves, if
installed.
3. Open the air relief valve by turning
it counter-clockwise two full turns.
This will relieve pressure in the tank.
4. Remove the drain plug (or open the
drain valve) and drain all water from
the tank.
5. Press the safety latch toward the
tank to release it from the locking
ring.
6. While holding the safety latch in the
release position, turn the locking
ring counter-clockwise to remove it
(approximately 1/2 turn). If the ring
is difficult to turn, tap it gently with
a rubber mallet to overcome the
initial resistance.
Cartridge Cleaning
When to clean the filter: The filter
cartridge should normally be removed
and cleaned when the pressure gauge
reads 8 psi to 10 psi (55 kPa - 69 kPa)
above the start-up pressure noted
below:
Installation date: __________________
Start-up pressure: __________________
Cleaning pressure: __________________
In some pools and spas, accessories
such as fountains, waterfalls, and pool
cleaners may be noticeably affected by
the normal decrease in flow as the filter
becomes dirty. If so, these systems may
require more frequent cleaning (that is,
at a pressure increase of less than 10 psi)
to operate properly.
The cleaning interval is based on
pressure rise, not on operation time.
Different water conditions will lead to
different cleaning intervals.
NOTE:
To limit the down time of the
filter, keep a second cartridge on hand.
This will allow time to properly clean
the cartridge and also will allow for
immediate replacement should one
filter cartridge fail.
when using PhmB
(polyhexamethylene
biguanide) based sanitizers, such as
Baquacil
®
, special care must be taken
when cleaning the cartridge. Cartridges
in systems using these sanitizers
must be cleaned more frequently and
thoroughly than chlorine systems.
PhmB based sanitizers also require the
use of special PhmB cleaners. Carefully
follow the PhmB sanitizer/cleaner
manufacturer's instructions when
cleaning the filter. use of any other
type of cleansers with PhmB sanitizers
will permanently clog the filter and will
void the filter warranty
1. Follow all steps in the "Filter
Disassembly" section of this manual.
2. With drain plug removed, flush any
foreign material from the inside of
the tank before removing the filter
cartridge.
3. Allow the tank to drain.
4. Carefully pull the cartridge straight
up from the filter base, avoiding
contact with the flow diverter.
5. Using a garden hose with a nozzle,
clean the cartridge thoroughly.
Work from the top down, holding
the nozzle at a 45° angle. Spray all
the pleats, with emphasis between
the pleats, until all dirt and debris is
gone. Allow the cartridge to drain.
6. For cartridges used where
perspiration, suntan lotions, and
other oils are present, soak the
element for at least one hour
(overnight is recommended) in one
of the following:
a. Commercial filter cleaner
(follow the manufacturer’s
directions)
b. Solution of one cup (8 fl oz)
trisodium phosphate (TSP) and
five gallons water.
c. Solution of one cup (8 fl oz)
dishwasher detergent and five
gallons of water.
7. Thoroughly rinse the cartridge again
to remove cleaning solution and oils.
8. Inspect the cartridge for cleanliness
and damage. If necessary, repeat the
washing process. If the cartridge is
damaged, replace it.
Failure to remove
all oils and cleaning
solution before soaking cartridge in
acid will permanently damage the filter
cartridge.
9. If the filter has a coating of algae,
calcium carbonate (residue from
calcium hypochlorite), iron or other
minerals, soak the cartridge in a
solution of one part muriatic acid
to twenty parts water (6 fl oz per
gallon of water) until all bubbling
stops.
wear
rubber
gloves, protective clothing
and safety goggles when
using acid. Do not add water
to acid, as splashing of full
strength acid could result.
10. Thoroughly rinse the cartridge to
remove all acid solution.
when this
procedure no longer
adequately cleans the cartridge, discard
the cartridge and replace it with a new
one.
11. Carefully follow the steps in the
“Filter Assembly” section of this
manual.
